In the past, cruise ships in various places broke out of the Nuo Ru virus incident. This time, the Diamond Princess Cruise had at least 135 people diagnosed with new coronary virus pneumonia.Some experts point out that compared with aircraft, ships, buses, and trains have a high risk of infection cases, because the air filtering system of the aircraft can deal with bacterial viruses, and the overall airflow will also make droplets falling faster to the ground.
The airflow of the cabin filtration system is pressed down the droplets
The air filtration system in the cabin will block bacteria and viruses, and the airflow of the cabin is sinking, which will reduce the droplets to the ground faster and reduce the risk of other people's infection.On the contrary, he believes that the risk of the bus group will be higher because passengers sit side by side for a long time.Last month, an Osaka tour guide and a tourist driver suspected to be infected by a tour group from Wuhan.
Professor Saito, Professor of Niigata University, pointed out that in the past, there were too many influenza or a virus explosion in the previous cruise ships. There were 1/3 of the crew members of the influenza.According to the number of US Centers for Disease Control and Prevention (CDC) in 2019, there are 8 cases of cruise outbreaks in the year, involving 7 ships.
